Recycled aggregate concrete refers to a new type of concrete material made by processing waste concrete materials through grading, crushing, and cleaning, and then mixing them with cement, water, and other materials in a certain gradation or proportion. This type of concrete is highly suitable for modern construction waste disposal and reuse and has been widely used in various construction projects. It can also be used as an environmentally friendly permeable brick material to promote the development of modern green buildings. However, practical applications have found that compared to ordinary concrete, the durability of this type of concrete is more susceptible to high-temperature and complex environments. Based on this, this paper conducts theoretical research on its durability in high-temperature and complex environments, including the current research status, existing problems, and application prospects of recycled aggregate concrete’s durability in such environments. It is hoped that this analysis can provide some reference for studying the influence of high-temperature and complex environments on recycled aggregate concrete and its subsequent application strategies.
